Speaking at DelphiLive in San Jose, USA

11. March 2009 in .NET, Delphi | No comments

A few days ago I was notified that two of my abstracts have been accepted for DelphiLive! Thus, I will be at the conference in May. Hopefully, I will be able to meet a lot of people in the Delphi Community I have not met so far as they cannot travel to Germany so easily.

My first session will be designed for the Delphi VCL programmer who wants to start with… Continue reading

Holger back to duty…well, almost

This post has been in my head for quite some time. I never knew how to get started, but a Sunday seemed like the right time to do it.

You did not read anything from me recently. Not on the newsgroups, not on my blog. If you communicate with me directly, even email and Skype was not being answered for a long time.There is a reason. A hardware related one. Sadly… Continue reading

Starting today, there will be two code camps per day. Go to www.entwickler-akademie.de to get a list of sessions.

We used Delphi 2009 and the crowd was rather pleased with the efficiency, speed and reliability of the… Continue reading

XtraTreeList: Which element in my IList<> is selected?

1. August 2008 in .NET | No comments

Let us look at some common means that different frameworks use to deliver a result to this question.

As I mentioned before, I mostly used the standard .NET components or VCL controls. Data-based VCL controls can be bound to TDataSource (and derivatives due to polymorphism). If an item is being selected, the cursor in the source moves accordingly. Thus, there is no difficulty to determine which row in the dataset it… Continue reading

XtraTreeView: Display a tree structure easily (Binding to an IList<> data source)

31. July 2008 in .NET | 4 comments

Today I found yet another example that most blog posts do not need to describe something extremely complicated to be helpful. I was talking to a co-worker at University about the fact that the standard TreeView control that is being delivered with the .NET libraries is a bit unusual to use. Especially, binding data to it is not an easy thing to do.

I immediately thought of XtraTreeView by DevExpress, which… Continue reading
